The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Development is the sum of growth and differentiation." - Development in plants encompasses all changes that occur throughout their life cycle, from germination to senescence (the process of aging and death). - Growth refers to an increase in size or mass, while differentiation involves the process by which cells become specialized to perform specific functions. - Therefore, the assertion is true as development indeed includes both growth and differentiation. 2. **Understanding the Reason**: - The reason states that "Development in plants is under the control of extrinsic factors only." - Extrinsic factors are external influences such as light, temperature, water, and nutrients that can affect plant development. - However, plant development is also influenced by intrinsic factors, which include genetic material (DNA and genes) that regulate growth and differentiation. - Since the reason claims that development is controlled solely by extrinsic factors, it is false because it neglects the role of intrinsic factors. 3. **Conclusion**: - The assertion is true, while the reason is false. Therefore, the correct answer to the question is that the assertion is true but the reason is false. ### Final Answer: The correct option is: **Third - Assertion is true but reason is false.**
